Boeing 777-9 undergoing VMU (Velocity Minimum Unstick) testing. This certification test determines the minimum speed at which the aircraft can safely take off. During the test, the jet accelerates to takeoff speed and is pitched to its maximum angle of attack until the tail drags on the ground. The... show more

Velocity Minimum Unstick testing of Airbus airliners: These involve pitching up as early as possible on the runway and dragging the tail against the ground in a shower of sparks until the wheels leave the ground.

The Boeing 777-9 underwent maximum brake energy certification testing at Edwards Air Force Base, demonstrating its ability to safely stop under demanding conditions following a rejected takeoff. During the test, brake temperatures reached as high as 2,500°F (1,371°C).

.Air India's first A350-1000 was spotted by Eurospot in Toulouse while undergoing the rejected takeoff test. Worn out brakes (installed on the aircraft for this test) are slammed at take off speed and the aircraft must come to a complete stop. #AvGeek

20 January 1974. First 'accidental' flight of the General Dynamics F-16 Fighting Falcon, US multirole jet fighter aircraft. During high-speed taxi test, the GD test pilot, Phil Oestricher, decided to lift off to avoid crashing the machine, and safely landed it six minutes later.

This is one of the most punishing certification tests any airliner must survive - Rejected Takeoff (RTO) For certification, Boeing accelerates the 777 to just below V1 at around 775,000 lb (351 tons), then cuts thrust and applies maximum braking. The airplane has seconds to go from full power to a complete stop. The sideways drift comes from pure physics: enormous inertia, uneven tire grip, and an anti-skid system riding the edge of a skid. Brake temperatures spike until they glow, and fuse plugs in the wheels are designed to let the tires deflate safely if they get too hot.

During a test flight over the Pacific off the coast of California, a Boeing 717 entered an intentional stall and rolled inverted. The maneuver was unplanned, but the test crew responded immediately, regaining control by reducing engine thrust and deploying speed brakes, ultimately recovering the aircraft.

A LATAM Boeing 777 aborted a high-speed takeoff last night (15). Via AEROIN The Boeing 777-300ER, registration PT-MUH, was in the takeoff roll when the pilots decided to abort at very high speed. According to our data, the decision was made at approximately 178 knots (330 km/h), at a moment when the nose gear had already lifted off the runway. The reason for the rejected takeoff has not yet been disclosed. 🎥 Video source: Aviação Guarulhos JPD ✈️ Flight data:

In case you were wondering, this is how it works. A towbarless aircraft tug is used to push an aircraft back from the gate. Instead of using a towbar, it drives up to the nose wheels, clamps them in place and lifts the nose landing gear slightly off the ground. The main landing gear stays on the ground at all times. Once secured, the tug controls the steering and carefully pushes the aircraft into position for taxi. Only a small part of the aircraft's weight rests on the nose gear which is why even large aircraft like the Boeing 777 can be moved safely and smoothly. After pushback, the tug lowers the nose wheels and disconnects, and the pilots continue taxiing.

Rare visuals of a "Tail cone evacuation slide" in action when a Delta Airlines Boeing 717, which departed Atlanta for Columbia, South Carolina, returned back after smoke filled the cabin mid-flight, prompting a safe evacuation. The tail slide on the Boeing 717 got deployed after the rear cone was Jettisoned from the fuselage. Some of the aircraft like MD-83 & B717 have a tail cone emergency exit in the tail cone at the aft end of the passenger cabin. How does tail cone emergency slide work? -If the emergency exits are armed & the handle located in the door of the aft passenger entrance is actuated, the tail cone detaches & the slide deploys automatically. -On actuation, the tail cone releases & falls. It then turns 90° & moves to the left side of the aircraft to keep the tail cone from interfering with the deployment of the slide. -Jettison & slide deploy uses a set of clasps & cables which are attached to a bar on the door & to the clamping bolts on the tail cone. -The tailcone exit may be actuated from two more locations, 👉 A handle on the inside of the tail cone (non-pressurized area). 👉 Another handle on the outside of the aircraft. -The Boeing 717 twin-engine airliner produced by Boeing Commercial Airplanes was developed for the 100-seat market and originally marketed by McDonnell Douglas in the early 1990s as the MD-95 until the company merged with Boeing in August 1997.

NEW ISSUE HITS BOEING 777X PROGRAM Boeing has identified a new durability issue affecting the GE9X engines powering the long-delayed 777-9, adding to the program’s ongoing technical challenges. The issue was discovered during a recent engine inspection and confirmed by Boeing during its full-year earnings briefing. Boeing says it is working closely with GE Aerospace, which has launched an on-wing inspection program while the root cause is analyzed and corrective actions are defined. Boeing has not disclosed the specific components involved but emphasized that certification flight testing continues and the current flight test campaign remains unaffected. CEO Kelly Ortberg stated that the company does not expect the issue to delay entry into service, which is still targeted for 2027. Originally planned to enter service in 2020, the 777-9 has faced repeated delays due to certification hurdles and technical findings.
